Had the Terry Butterfly for years, but always experienced a *little* chafing in the tender parts, so when it was time for a new saddle I went with the Terry Falcon thinking that the larger cutout would be good. It WAS...no more chafing...but after a couple of months of consistent riding (3x week minimum, anywhere from 25-80 miles each ride) I have these hard lumps in the crease between my thigh and my crotch. I can only think it's the shape - the falcon is more "pear shaped" and I think it puts pressure where none is desired. So I'm back to the drawing board.
